Methods of treating or reducing the risk of cardiovascular events and related diseases using sglt-2 inhibitors

ABSTRACT

The present invention relates to the use of certain SGLT-2 inhibitors, such as ertugliflozin or a pharmaceutically acceptable salt or a co-crystal thereof, for treating, reducing the risk of and/or preventing heart failure, myocardial infarction, cardiovascular disease or cardiovascular death in animals without type 2 or type 1 diabetes mellitus, or in animals with pre-diabetes, or in animals with type 2 or type 1 diabetes mellitus or pre-diabetes.

FIELD OF THE INVENTION

The present invention relates to the use of certain SGLT-2 inhibitors, such as ertugliflozin or a pharmaceutically acceptable salt or a co-crystal thereof, for treating, reducing the risk of and/or preventing heart failure, myocardial infarction, cardiovascular disease or cardiovascular death in animals, preferably humans, without type 2 or type 1 diabetes mellitus or pre-diabetes, or in animals, preferably humans, with type 2 or type 1 diabetes mellitus or pre-diabetes.

BACKGROUND

Sodium-glucose co-transport (SGLT) inhibitors have been found to be effective in treating pre-diabetes, type 1 or type 2 diabetes mellitus. Particularly, SGLT-2 inhibitors have been shown to block the reabsorption of glucose from the renal filtrate in the glomerulus thereby inducing glucose excretion in the urine. As excess glucose is excreted, there is a decrease in blood glucose level, decreased hepatic storage of glucose, decreased insulin secretion and, subsequently, decreased carbohydrate conversion to fat and, ultimately, reduced accumulated fat. Selective inhibition of SGLT-2 is expected to normalize plasma glucose by enhancing glucose excretion. Consequently, SGLT-2 inhibitors provide an attractive means to improve diabetic conditions without increasing body weight or the risk of hypoglycemia. See, Isaji, M., Current Opinion Investigational Drugs, 8(4), 285-292 (2007). For a general review of SGLT as a therapeutic target, see also Asano, T., et al., Drugs of the Future, 29(5), 461-466 (2004).

Since the mode of action of SGLT-2 inhibitors is independent of insulin secretion, SGLT-2 inhibitors are associated with a low risk of hypoglycemia, which has been linked to increased cardiovascular events. Inzucchi et al., Diabetes & Vascular Disease Research, 12(2), 90-100 (2015). Recently, results of the effects of the SGLT-2 inhibitor, empagliflozin, in addition to the standard of care, on cardiovascular morbidity and mortality in animals with type 2 diabetes at high cardiovascular risk were published. While the results showed no significant between-group differences in the rates of myocardial infarction or stroke, in the empagliflozin group there were significantly lower rates of death from cardiovascular causes (3.7% vs. 5.9% in the placebo group; 38% relative risk reduction), hospitalization for heart failure (2.7% and 4.1%, respectively; 35% relative risk reduction), and death from any cause (5.7% and 8.3%, respectively; 32% relative risk reduction). Zinman et al., Empagliflozin, Cardiovascular Outcomes, and Mortality in Type 2 Diabetes, N. Engl. J. Med. 373; 22, 2117-2128 (2015). The biomarker effects of SGLT-2 inhibitors in diabetics are similar to those in non-diabetics. For example, both populations (diabetics and non-diabetics) experience increases in urinary glucose excretion and an osmotic diuretic effect. Liu et al., Why Do SGLT-2 Inhibitors Inhibit Only 30-50% of Renal Glucose Reabsorption in Humans?, Diabetes, 61, 2199-2204 (2012).

SUMMARY

The present invention relates to the use of certain SGLT-2 inhibitors for treating, reducing the risk and/or preventing heart failure, myocardial infarction, cardiovascular disease or cardiovascular death in animals without type 2 or type 1 diabetes.

Additionally, the present invention relates to the use of certain SGLT-2 inhibitors for treating, reducing the risk and/or preventing heart failure, myocardial infarction, cardiovascular disease or cardiovascular death in animals with type 2 or type 1 diabetes mellitus.

It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. The plural and singular should be treated as interchangeable, other than the indication of number.

As used herein, the term “alkyl” refers to a hydrocarbon radical of the general formula C_(n)H_(2(n+1)). The alkane radical may be straight or branched. For example, the term “(C₁-C₆)alkyl” refers to a monovalent, straight, or branched aliphatic group containing 1 to 6 carbon atoms (e.g., methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, s-butyl, t-butyl, n-pentyl, 1-methylbutyl, 2-methylbutyl, 3-methylbutyl, neopentyl, 3,3-dimethylpropyl, hexyl, 2-methylpentyl, and the like). Similarly, the alkyl portion (i.e., alkyl moiety) of an alkoxy, acyl (e.g., alkanoyl), alkylamino, dialkylamino, alkylsulfonyl, and alkylthio group have the same definition as above. When indicated as being “optionally substituted”, the alkane radical or alkyl moiety may be unsubstituted or substituted with one or more substituents (generally, one to three substituents except in the case of halogen substituents where it means a complete substitution of halogen for hydrogen such as perchloro or perfluoroalkyls) independently selected from the group of substituents listed below in the definition for “substituted.” “Halo-substituted alkyl” refers to an alkyl group substituted with one or more halogen atoms (e.g., fluoromethyl, difluoromethyl, trifluoromethyl, perfluoroethyl, 1,1-difluoroethyl and the like).

The term “cycloalkyl” refers to nonaromatic rings and may exist as a single ring, bicyclic ring or a spiro ring. Unless specified otherwise, the carbocyclic ring is generally a 3- to 8-membered ring. For example, cycloalkyl include groups such as cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cyclohexenyl, norbornyl (bicyclo[2.2.1]heptyl), bicyclo[2.2.2]octyl, and the like.

The term “heterocycle” refers to nonaromatic rings and may exist as a single ring, bicyclic ring or a spiro ring. Unless specified otherwise, the heterocyclic ring is generally a 3- to 6-membered ring containing 1 to 3 heteroatoms (preferably 1 or 2 heteroatoms) independently selected from sulfur, oxygen and/or nitrogen. Heterocyclic rings include groups such as epoxy, aziridinyl, tetrahydrofuranyl, pyrrolidinyl, N-methylpyrrolidinyl, piperidinyl, piperazinyl, pyrazolidinyl, 4H-pyranyl, morpholino, thiomorpholino, tetrahydrothienyl, tetrahydrothienyl 1,1-dioxide, and the like.

The phrase “therapeutically effective amount” means an amount of a compound of the present invention that (i) treats the particular disease, condition, or disorder, (ii) attenuates, ameliorates, or eliminates one or more symptoms of the particular disease, condition, or disorder, or (iii) prevents, reduces the risk of, or delays the onset of one or more symptoms of the particular disease, condition, or disorder described herein.

The term “animal” refers to humans (male or female), companion animals (e.g., dogs, cats and horses), food-source animals, zoo animals, marine animals, birds and other similar animal species. In specific embodiments herein, animal refers to humans.

The phrase “pharmaceutically acceptable” indicates that the substance or composition must be compatible chemically and/or toxicologically, with the other ingredients within a formulation, and/or the mammal being treated therewith.

The terms “treating”, “treat”, or “treatment” refers to the management and care of an animal, in particular, the attenuation, amelioration, or elimination of one or more symptoms of a particular disease, condition, or disorder.

The terms “modulated” or “modulating”, or “modulate(s)”, as used herein, unless otherwise indicated, refers to the inhibition of the sodium-glucose transporter (in particular, SGLT-2) with compounds of the present invention thereby partially or fully preventing glucose transport across the transporter.

The term “preventing”, as used herein, unless otherwise indicated, refers to thwarting or stopping the occurrence of a cardiovascular event, such as heart failure, myocardial infarction, or cardiovascular death, or thwarting or stopping the onset of cardiovascular disease.

The phrase “reduce the risk”, as used herein, unless indicated, refers to reducing the likelihood or severity of a cardiovascular event, such as heart failure, myocardial infarction, or cardiovascular death, or reducing the likelihood or severity of cardiovascular disease.

The terms “compounds” or “compounds of the present invention” (unless specifically identified otherwise) refer to compounds of Formula (A), Formula (B) and all pure and mixed stereoisomers (including diastereoisomers and enantiomers), tautomers and isotopically labeled compounds. Hydrates and solvates of the compounds of the present invention are considered compositions of the present invention, wherein the compound is in association with water or solvent, respectively. The compounds may also exist in one or more crystalline states, i.e. as co-crystals, polymorphs, or they may exist as amorphous solids.

Compounds used in the methods of the present invention may be synthesized by synthetic routes that include processes analogous to those well-known in the chemical arts, particularly in light of the description contained herein. The starting materials are generally available from commercial sources such as Aldrich Chemicals (Milwaukee, Wis.) or are readily prepared using methods well known to those skilled in the art (e.g., prepared by methods generally described in Louis F. Fieser and Mary Fieser, Reagents for Organic Synthesis, v. 1-19, Wiley, New York (1967-1999 ed.), or Beilsteins Handbuch der organischen Chemie, 4, Aufl. ed. Springer-Verlag, Berlin, including supplements (also available via the Beilstein online database)).

For illustrative purposes, the reaction schemes depicted below provide potential routes for synthesizing the compounds of the present invention as well as key intermediates. Those skilled in the art will appreciate that other synthetic routes may be used to synthesize the inventive compounds. Although specific starting materials and reagents are depicted in the schemes and discussed below, other starting materials and reagents can be easily substituted to provide a variety of derivatives and/or reaction conditions. In addition, many of the compounds prepared by the methods described below can be further modified in light of this disclosure using conventional chemistry well known to those skilled in the art.

In the preparation of compounds of the present invention, protection of remote functionality of intermediates may be necessary. The need for such protection will vary depending on the nature of the remote functionality and the conditions of the preparation methods. A “hydroxy-protecting group” refers to a substituent of a hydroxy group that blocks or protects the hydroxy functionality. Suitable hydroxyl-protecting groups (O-Pg) include for example, allyl, acetyl (Ac), silyl (like trimethylsilyl (TMS) or tert-butyldimethylsilyl (TBS)), benzyl (Bn), para-methoxybenzyl (PMB), trityl (Tr), para-bromobenzoyl, para-nitrobenzoyl and the like (e.g. benzylidene for protection of 1,3-diols). The need for such protection is readily determined by one skilled in the art. For a general description of protecting groups and their use, see T. W. Greene, Protective Groups in Organic Synthesis, John Wiley & Sons, New York, 1991.

Scheme 1 outlines the general procedures one could use to provide compounds of the present invention.

Allyl 2,3,4-tri-O-benzyl-D-glucopyranoside (I-a, where Pg′ is a benzyl group) can be prepared by procedures described by Shinya Hanashima, et al., in Bioorganic & Medicinal Chemistry, 9, 367 (2001); Patricia A. Gent et al. in Journal of the Chemical Society, Perkin 1, 1835 (1974); Hans Peter Wessel in the Journal of Carbohydrate Chemistry, 7, 263, (1988); or Yoko Yuasa, et al., in Organic Process Research & Development, 8, 405-407 (2004). In step 1 of Scheme 1, the hydroxymethylene group can be introduced onto the glycoside by means of a Swern oxidation followed by treatment with formaldehyde in the presence of an alkali metal hydroxide (e.g., sodium hydroxide). This is referred to as an aldol-Cannizzaro reaction. The Swern oxidation is described by Kanji Omura and Daniel Swern in Tetrahedron, 34, 1651 (1978). Modifications of this process known to those of skill in the art may also be used. For example, other oxidants, like stabilized 2-iodoxybenzoic acid described by Ozanne, A. et al. in Organic Letters, 5, 2903 (2003), as well as other oxidants known by those skilled in the art can also be used. The aldol Cannizzaro sequence has been described by Robert Schaffer in the Journal of The American Chemical Society, 81, 5452 (1959) and Amigues, E. J., et al., in Tetrahedron, 63, 10042 (2007).

In step 2 of Scheme 1, protecting groups (Pg²) can be added by treating intermediate (I-b) with the appropriate reagents and procedures for the particular protecting group desired. For example, p-methoxybenzyl (PMB) groups may be introduced by treatment of intermediate (I-b) with p-methoxybenzyl bromide or p-methoxybenzyl chloride in the presence of sodium hydride, potassium hydride, potassium tert-butoxide in a solvent like tetrahydrofuran, 1,2-dimethoxyethane or N,N-dimethylformamide (DMF). Conditions involving para-methoxybenzyltrichloroacetimidate in presence of a catalytic amount of acid (e.g., trifluoromethanesulfonic acid, methanesulfonic acid, or camphorsulfonic acid) in a solvent such as dichloromethane, heptane or hexanes can also be used. Benzyl (Bn) groups may be introduced by treatment of intermediate (I-b) with benzyl bromide or benzyl chloride in the presence of sodium hydride, potassium hydride, potassium tert-butoxide in a solvent like tetrahydrofuran, 1,2-dimethoxyethane or N,N-dimethylformamide. Conditions involving benzyltrichloroacetimidate in presence of a catalytic amount of acid (e.g., trifluoromethanesulfonic acid, methanesulfonic acid, or camphorsulfonic acid) in a solvent such as dichloromethane, heptane or hexanes can also be used.

In step 3 of Scheme 1, the allyl protection group is removed (e.g., by treatment with palladium chloride in methanol; cosolvent like dichloromethane may also be used; other conditions known by those skilled in the art could also be used, see T. W. Greene, Protective Groups in Organic Synthesis, John Wiley & Sons, New York, 1991) to form the lactol (I-d). In step 4 of Scheme 1, oxidation of the unprotected hydroxyl group to an oxo group (e.g., Swern oxidation) then forms the lactone (I-e).

In step 5 of Scheme 1, the lactone (I-e) is reacted with N,O-dimethyl hydroxylamine hydrochloride to form the corresponding Weinreb amide which may exist in equilibrium in a closed/opened form. (I-f/I-g). The “Weinreb amide” (I-g) can be made using procedures well known to those of skill in the art. See, Nahm, S., and S. M. Weinreb, Tetrahedron Letters, 22 (39), 3815-1818 (1981). For example, intermediate (I-f/I-g) can be prepared from the commercially available N,O-dimethylhydroxylamine hydrochloride and an activating agent (e.g., trimethylaluminum).

In step 6 of Scheme 1, the aryl benzyl group (Ar) is introduced using the desired organometallic reagent (e.g., organo lithium compound (ArLi) or organomagnesium compound (ArMgX)) in tetrahydrofuran (THF) at a temperature ranging from about −78° C. to about 20° C. followed by hydrolysis (upon standing in protic conditions) to the corresponding lactol (I-i) which may be in equilibrium with the corresponding ketone (I-h). The bridged ketal motif found in (A) and (B) can be prepared by removing the protecting groups (Pg²) using the appropriate reagents for the protecting groups employed. For example, the, p-methoxybenzyl (PMB) protecting groups may be removed by treatment with trifluoroacetic acid in the presence of anisole and dichloromethane (DCM) at about 0° C. to about 23° C. (room temperature). The remaining protecting groups (Pg¹) may then be removed using the appropriate chemistry for the particular protecting groups. For example, benzyl protecting groups may be removed by treating with formic acid in the presence of palladium (Pd black) in a protic solvent (e.g., ethanol/THF) at about room temperature to produce the final products (A) and (B). When R¹ is CN, the use of a Lewis acid like boron trichloride at a temperature ranging from about −78° C. to about room temperature in a solvent like dichloromethane or 1,2-dichloroethane may also be used to remove benzyl protective and/or para-methoxybenzyl protective groups.

When R¹ is CN and R² is (C₁-C₄)alkoxy in intermediate (I-i) or in products (A) or (B), upon treatment with a Lewis acid such as boron trichloride or boron tribromide, partial to complete de-alkylation to the corresponding phenol may occur to lead to the corresponding compound (A) or (B) where R¹ is CN and R² is OH. If this occurs, the (C₁-C₄)alkoxy group may be re-introduced via selective alkylation using a (C₁-C₄) alkyl iodide under mildly basic conditions, for example, potassium carbonate in acetone at a temperature ranging from about room temperature to about 56 degrees Celsius.

When R¹ and/or R² is (C₁-C₄)alkyl-SO₂— it is understood by one skilled in the art that the organometallic addition step 6 (Scheme 1) will be carried out on the corresponding (C₁-C₄)alkyl-S— containing organometallic reagent. The thio-alkyl is then oxidized at a later stage to the corresponding sulfone using conventional methods known by those skilled in the art.

The compounds of the present invention may be prepared as co-crystals using any suitable method. A representative scheme for preparing such co-crystals is described in Scheme 2.

In Scheme 2, wherein Me is methyl and Et is ethyl, in step 1, 1-(5-bromo-2-chlorobenzyl)-4-ethoxybenzene is dissolved in 3:1, toluene: tetrahydrofuran followed by cooling the resulting solution to <−70° C. To this solution is added hexyllithium while maintaining the reaction at ≤−65° C. followed by stirring for 1 hour. (3R,4S,5R,6R)-3,4,5-tris(trimethylsilyloxy)-6-((trimethylsilyloxy)methyl)-tetrahydropyran-2-one (II-a) is dissolved in toluene and the resulting solution is cooled to −15° C. This solution is then added to the −70° C. aryllithium solution followed by stirring for 1 hour. A solution of methanesulfonic acid in methanol is then added followed by warming to room temperature and stirring for 16 to 24 hours. The reaction is deemed complete when the α-anomer level is ≤3%. The reaction is then basified by the addition of 5 M aqueous sodium hydroxide solution. The resulting salts are filtered off followed by concentration of the crude product solution. 2-methyltetrahydrofuran is added as a co-solvent and the organic phase is extracted twice with water. The organic phase is then concentrated to 4 volumes in toluene. This concentrate is then added to a 5:1, heptane: toluene solution causing precipitate to form. The solids are collected and dried under vacuum to afford a solid.

In step 2 of Scheme 2, to (II-b) in methylene chloride is added imidazole followed by cooling to 0° C. and then addition of trimethylsilylchloride to give the persilylated product. The reaction is warmed to room temperature and quenched by the addition of water, and the organic phase is washed with water. This crude methylene chloride solution of (II-c) is dried over sodium sulfate and then taken on crude into the next step.

In step 3 of Scheme 2, the crude solution of (II-c) in methylene chloride is concentrated to low volume and then the solvent is exchanged to methanol. The methanol solution of (II-c) is cooled to 0° C., then 1 mol % of potassium carbonate is added as a solution in methanol followed by stirring for 5 hours. The reaction is then quenched by addition of 1 mol % acetic acid in methanol, followed by warming to room temperature, solvent exchange to ethyl acetate, and then filtration of the minor amount of inorganic solids. The crude ethyl acetate solution of (II-d) is taken directly into the next step.

In step 4 of Scheme 2, the crude solution of (II-d) is concentrated to low volume, then diluted with methylene chloride and dimethylsulfoxide. Triethylamine is added followed by cooling to 10° C. and then sulfur trioxide pyridine complex is added in 3 portions as a solid at 10 minute intervals. The reaction is stirred an additional 3 hours at 10° C. before quenching with water and warming to room temperature. The phases are separated followed by washing the methylene chloride layer with aqueous ammonium chloride. The crude methylene chloride solution of (II-e) is taken directly into the next step.

In step 5 of Scheme 2, the crude solution of (II-e) is concentrated to low volume and then the solvent is exchanged to ethanol. Thirty equivalents of aqueous formaldehyde is added followed by warming to 55° C. An aqueous solution of 2 equivalents of potassium phosphate, tribasic is added followed by stirring for 24 hours at 55° C. The reaction temperature is then raised to 70° C. for an additional 12 hours. The reaction is cooled to room temperature, diluted with tert-butyl methyl ether and brine. The phases are separated followed by solvent exchange of the organic phase to ethyl acetate. The ethyl acetate phase is washed with brine and concentrated to low volume. The crude concentrate is then purified by silica gel flash chromatography eluting with 5% methanol, 95% toluene. Product containing fractions are combined and concentrated to low volume. Methanol is added followed by stirring until precipitation occurs. The suspension is cooled and the solids are collected and rinsed with heptane followed by drying. Product (II-0 is isolated as a solid.

In step 6 of Scheme 2, compound (II-0 is dissolved in 5 volumes of methylene chloride followed by the addition of 1 mol % SiliaBond® tosic acid and stirring for 18 hours at room temperature. The acid catalyst is filtered off and the methylene chloride solution of (II-g) is taken directly into the next step co-crystallization procedure.

In step 7 of Scheme 2, the methylene chloride solution of (II-g) is concentrated and then the solvent is exchanged to 2-propanol. Water is added followed by warming to 55° C. An aqueous solution of L-pyroglutamic acid is added followed by cooling the resulting solution to room temperature. The solution is then seeded and granulated for 18 hours. After cooling, the solids are collected and rinsed with heptane followed by drying. Product (II-h) is isolated as a solid.

An alternative synthesis route for compounds (A) of the present invention is depicted in Scheme 3 and described below.

The synthesis of (III-a), where R₃ is an alkyl or fluoro substituted alkyl (except for the carbon adjacent to the oxygen atom) can be prepared in a similar way as described in step 1 of Scheme 2. In step 1 of Scheme 3, the primary hydroxyl group is selectively protected by an appropriate protective group. For example, a trityl group (Pg₃=Tr) can be introduced by treatment of intermediate (III-a) with chlorotriphenylmethane in presence of a base like pyridine in a solvent like toluene, tetrahydrofuran or dichloromethane at a temperature ranging from about 0 degrees Celsius to about room temperature. Additional examples of such protective groups and experimental conditions are known by those skilled in the art and can be found in T. W. Greene, Protective Groups in Organic Synthesis, John Wiley & Sons, New York, 1991. In step 2 of Scheme 3, the secondary hydroxyl groups can be protected by the appropriate protecting groups. For example, benzyl groups (Pg₄ is Bn) can be introduced by treatment of intermediate (III-b) with benzyl bromide or benzyl chloride in the presence of sodium hydride, potassium hydride, potassium tert-butoxide in a solvent like tetrahydrofuran, 1,2-dimethoxyethane or N,N-dimethylformamide at a temperature ranging from about 0 degrees Celsius to about 80 degrees Celsius. Acetyl or benzoyl groups (Pg₄=Ac or Bz) may be introduced by treatment of intermediate (III-b) with acetyl chloride, acetyl bromide or acetic anhydride, benzoyl chloride or benzoic anhydride in the presence of a base like triethylamine, N,N-diisopropylethylamine or 4-(dimethylamino)pyridine in a solvent like tetrahydrofuran, 1,2-dimethoxyethane or dichloromethane at a temperature ranging from about 0 degrees Celsius to about 80 degrees Celsius.

In step 3 of Scheme 3, the primary hydroxyl group is deprotected to lead to intermediate (III-d). When Pg₃ is Tr, intermediate (III-c) is treated in the presence of an acid like para-toluenesulfonic acid in an alcoholic solvent like methanol at a temperature ranging from about −20 degrees Celsius to about room temperature to provide intermediate (III-d). Cosolvents like chloroform may be used.

In step 4 of Scheme 3, a hydroxymethylene group is introduced through a process similar to the one already described in Scheme 1 (step 1) and Scheme 2 (steps 4 and 5). Other sources of formaldehyde, like paraformaldehyde in a solvent like ethanol at a temperature ranging from about room temperature to about 70 degrees Celsius in the presence of an alkali metal alkoxide can also be used in this step. When Pg₄ is Bn, this step provides intermediate (III-e) and when Pg₄ is Ac or Bz, this step provides intermediate (III-f).

In step 5 of Scheme 3, intermediate (III-e) is treated with an acid like trifluoroacetic acid or an acidic resin in a solvent like dichloromethane at a temperature ranging from about −10 degrees Celsius to about room temperature to produce intermediate (III-g).

In step 6 of Scheme 3, the remaining protecting groups (Pg₄) may then be removed using the appropriate chemistry for the particular protecting groups. For example, benzyl protecting groups may be removed by treating with formic acid in the presence of palladium (Pd black) in a protic solvent (e.g., ethanol/THF) at about room temperature to produce the final product (A).

In step 7 of Scheme 3, intermediate (III-0 is treated with an acid like trifluoroacetic acid or an acidic resin in a solvent like dichloromethane at a temperature ranging from about −10 degrees Celsius to about room temperature to produce the final product (A).

Another alternative scheme for synthesizing product (A) is depicted in Scheme 4 and described below.

In step 1 of Scheme 4, intermediate (III-a) is treated with the appropriate arylsulfonyl chloride R₄SO₂Cl or arylsulfonic anhydride R₄S(O)₂OS(O)₂R₄ (wherein R₄ is an optionally substituted aryl group, such as found in the arylsulfonyl chlorides 4-methyl-benzenesulfonyl chloride, 4-nitro-benzenesulfonyl chloride, 4-fluoro-benzenesulfonyl chloride, 2,6-dichloro-benzenesulfonyl chloride, 4-fluoro-2-methyl-benzenesulfonyl chloride, and 2,4,6-trichloro-benzenesulfonyl chloride, and in the arylsulfonic anhydride, p-toluenesulfonic anhydride) in presence of a base like pyridine, triethylamine, N,N-diisopropylethylamine in a solvent like tetrahydrofuran, 2-methyltetrahydrofuran at a temperature ranging from about −20 degrees Celsius to about room temperature. Some Lewis acids like zinc(II) bromide may be used as additives.

In step 2 of Scheme 4, intermediate (IV-a) is submitted to a Kornblum-type oxidation (see, Kornblum, N., et al., Journal of The American Chemical Society, 81, 4113 (1959)) to produce the corresponding aldehyde which may exist in equilibrium with the corresponding hydrate and/or hemiacetal form. For example intermediate (IV-a) is treated in the presence of a base like pyridine, 2,6-lutidine, 2,4,6-collidine, N,N-diisopropylethylamine, 4-(dimethylamino)pyridine in a solvent like dimethyl sulfoxide at a temperature ranging from about room temperature to about 150 degrees Celsius. The aldehyde intermediate produced is then submitted to the aldol/Cannizzaro conditions described for step 1 (Scheme 1) and step 5 (Scheme 2) to produce intermediate (IV-b).

In step 3 of Scheme 4, intermediate (IV-b) is treated with an acid like trifluoroacetic acid or an acidic resin in a solvent like dichloromethane at a temperature ranging from about −10 degrees Celsius to about room temperature to produce the final product (A). When R² is (C₂-C₄)alkynyl the process may be performed using Scheme 5, wherein R⁶ is H or (C₁-C₂)alkyl.

In step 1 of Scheme 5, which provides intermediate (V-i), the organometallic addition step is carried out in a similar way to the one described in Scheme 1, step 6, using the organometallic reagent derived from (V-a), where Pg₅ is a suitable protective group for the hydroxyl group. For instance Pg₅ can be a tert-butyldimethylsilyl group (TBS) (see US2007/0054867 for preparation of for instance {4-[(5-bromo-2-chloro-phenyl)-methyl]-phenoxy}-tert-butyl-dimethyl-silane).

In step 2 of Scheme 5, when Pg²=PMB, intermediate (V-i) is treated with an acid like trifluoroacetic acid, methanesulfonic acid or an acidic resin in presence of anisole in a solvent like dichloromethane at a temperature ranging from about −10 degrees Celsius to about room temperature to produce intermediate (V-j).

In step 3 of Scheme 5, protecting groups (Pg₅) and (Pg¹) can be removed to provide (V-k). Typically (Pg₅) is TBS and Pg¹ is Bn. In this circumstance, the protecting groups are removed by sequential treatment of (V j) with 1) tetrabutylammonium fluoride in a solvent like tetrahydrofuran or 2-methyltetrahydrofuran at a temperature ranging from 0 degrees Celsius to about 40 degrees Celsius and 2) treatment with formic acid in the presence of palladium (Pd black) in a protic solvent (e.g., ethanol/THF) at about room temperature. In this sequence, the order of the 2 reactions is interchangeable.

In step 4 of Scheme 5, intermediate (V-k) is treated with N,N-bis-(trifluoromethanesulfonyl)-aniline in presence of a base like triethylamine or 4-dimethyaminopyridine in a solvent like dichloromethane or 1,2-dichloroethane at a temperature ranging from 0 degrees Celsius to about 40 degrees Celsius to produce intermediate (V-1).

In step 5 of Scheme 5, intermediate (V-1) is subjected to a Sonogashira-type reaction (see, Sonogashira, K. Coupling Reactions Between sp² and sp Carbon Centers. In Comprehensive Organic Synthesis (eds. Trost, B. M., Fleming, I.), 3, 521-549, (Pergamon, Oxford, 1991)). For instance (V-1) is treated with the appropriate terminal alkyne HCCR⁶ in presence of copper(I) iodide, a catalyst like bis-(triphenylphosphine)-palladium dichloride or tetrakis(triphenylphosphine)palladium(0) in presence of a base like triethylamine or N,N-diisopropylethylamine in a solvent like N,N-dimethylformamide at a temperature ranging from about room temperature to about 120 degrees Celsius to produce the desired product (A) and (B). When R⁶ is H, it is more convenient to use trimethylsilylacetylene. In this case the crude material obtained from the reaction described above is treated with a base like potassium carbonate in an alcoholic solvent like MeOH at about room temperature to produce the desired product (A) and (B) where R² is —CCH after classical work-up known by those skilled in the art.

One skilled in the art would understand that the chemistry described above in schemes 1 to 5, represents different ways of accessing intermediate (V-k). In turn, particularly when R¹ is Cl, (V-k) can be treated with an alkylating agent of choice under classical conditions to selectively alkylate the phenol group to produce (A) (and (B) in schemes 1 and 5) where R² is (C₁-C₄)alkoxy.

The compounds of the present invention contain asymmetric or chiral centers, and, therefore, exist in different stereoisomeric forms. Unless a specific enationmer or diastereomer is indicated, the invention includes all possible enantiomers and diastereomers and mixtures of two or more stereoisomers, for example mixtures of enantiomers and/or diastereomers, in all ratios.

Diastereomeric mixtures can be separated into their individual diastereoisomers on the basis of their physical chemical differences by methods well known to those skilled in the art, such as by chromatography and/or fractional crystallization, distillation and sublimation. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereoisomers and converting (e.g., hydrolyzing) the individual diastereoisomers to the corresponding pure enantiomers. Also, some of the compounds of the present invention may be atropisomers (e.g., substituted biaryls) and are considered of use of this invention. Enantiomers can also be separated by use of a chiral HPLC (high pressure liquid chromatography) column.

It is also possible that the intermediates and compounds of the present invention may exist in different tautomeric forms, and all such forms are embraced within the scope of the invention. The term “tautomer” or “tautomeric form” refers to structural isomers of different energies which are interconvertible via a low energy barrier. For example, proton tautomers (also known as prototropic tautomers) include interconversions via migration of a proton, such as keto-enol and imine-enamine isomerizations. A specific example of a proton tautomer is the imidazole moiety where the proton may migrate between the two ring nitrogens. Valence tautomers include interconversions by reorganization of some of the bonding electrons. The equilibrium between closed and opened form of some intermediates (and/or mixtures of intermediates) is reminiscent of the process of mutarotation involving aldoses, known by those skilled in the art.

The present invention also embraces isotopically-labeled compounds of the present invention which are identical to those recited herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, iodine, and chlorine, such as ²H, ³H, ¹¹C, ¹³C, ¹⁴C, ¹³N, ¹⁵N, ¹⁵O, ¹⁷O, ¹⁸O, ³¹P, ³²P, ³⁵S, ¹⁸F, ¹²³I, ¹²⁵I and ³⁶Cl, respectively.

Certain isotopically-labeled compounds of the present invention (e.g., those labeled with ³H and ¹⁴C) are useful in compound and/or substrate tissue distribution assays. Tritiated (i.e., ³H) and carbon-14 (i.e., ⁴C) isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with alternative isotopes such as deuterium (i.e., ²H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances. Positron emitting isotopes such as ¹⁵O ¹³N, ¹¹C, and ¹⁸F are useful for positron emission tomography (PET) studies to examine substrate occupancy. Isotopically labeled compounds of the present invention can generally be prepared by following procedures analogous to those disclosed in the Schemes and/or in the description herein, by substituting an isotopically labeled reagent for a non-isotopically labeled reagent.
